' RAILROAD TIE.

Application led August 6, 1920. Seria1 No. 401,644.,

T o all 'whom it may concern.'

Be it known that I, GUs'rAvn MAN, a citizen of the Republic of Germany, residing at Detroit, in the county of Wayne and State of Michigamhave invented certain new and useful Improvements in Railroad Ties,'of which the following is a specification, reference being had therein to the accompanying drawings. l

This invention relates to reinforced concrete railroad-ties and has for its object to produce a durable and low priced construction which will have all the advantages of a wooden tie, a metal tie, anda concrete tie, without the usual disadvantages.

This andother objectsare accomplished by the present device, in which wood is used where its cushioning effect is desirable, metal where resiliency and strength `are needed, and 'concrete where compression strains are to be resisted, a composite tie having fastening means for the rails joined therewith and made with great economy of materials resulting.

In the drawing Figure 1 is a perspective view showing the general arrangement of a series of ties in position; y

Fig. 2 is a longitudinal section of a tie, one of the tie-rods being in elevation, and a portion of one tie block being broken awa-y to show some of the reinforcing rods in elevation;

Fig. 3 is a plan view;

Fig. 4 is a section of the clamp member; and

Fig. 5 is a horizontal section through a tie block on the line V-V of Fig. 2.

Each tie consists-of two blocks 10 and 11 made of reinforced concrete, and connected by two tie-tie rods 12 and 13. The ends of the tie rods are bent and extend upward above the surface of the tie blocks far enough to receive the cushion blocks 14 and 15, the clamp members 16 and the lock nuts 17.

It will be observed that the rods 12 and 13 are of the same length, and that they are set in the'blocks 10 and l1 -so that the upturned ends in each block are on opposite sides of the rails 21. Each rod extends from the inner side of one rail to the outer side of the other. The tie-rods' are a part of the reinforcement system of the blocks.

Each block 10 and 11 has a series of reinforcing elements consisting of bent steel rods laid substantially parallel with each A. WINKEL-- other and with the bottom of the block, the bent portions extending first outwardly and upwardly, then inwardly and upwardly, and at the ends substantially parallel with the upper face of the bloclr. These reinforcing elements 18 may be connected by cross wires 19 at their centralfportion beneath the place where the railwilly rest, as an additional reinforcement at the point of greatest strain,

and as a convenient way of holding 'the rods 18 assembled while being placed in the mold and .n during the concrete. l

In practice, the rodsl12 and 13-will be about l inches Vin diameter and the blocks` 10 jand. 11 will be about 9v inches thick,g10.

inches wide, rand 36 inches long, but vit will be understood that these dimensions maybe varied to suit varying conditions without departing from the spirit of my invention.

The cushioning blocks of wood 14, 15, will be about 4 inches thick, 10 inches wide, and

.15 inches long, and -will have holes bored` at the proper places to receive 'the upturned ends of the rods 12 and 13. The clamp members 16 may be rectangular blocks of steel having one corner beveled toengage thel lower flange of the rail 21, and provided with a hole 2O for the rod 12lor 13.

The lock" nuts 17 may be of any approvedy form.

s It will be obvious that any suitable molds may be used, 'the reinforcing rods and cross tie-rods being set in the proper'position and the concrete formed in the mold by pouring or filling and tamping, or by any other preferred method. Y

I claim:

1. A railway tie comprising two concrete blocks connected by flexible tie rods of equal lengths having their endsbent upward and pouring or packing of the,

spaced apart to receive a cushion block and a .l

rail, the ends of the rods in each block lying on opposite sides of the rail and being provided with clamping means to hold the lower flanges of the rail to the blocks.

2. A krailway tie comprising two spacedapart blocks of reinforced concrete connected by atie-rod traversing the blocks in two planes at an angle to each other, the ends of the tie-rod being positioned adjacent to the ange on the same side of each rail, and having a clamping means secured thereto.

1 3. A railway tie comprising two spacedapart blocks of reinforced concrete, connected by two tie-rods traversing the blocks, in

two planes at an angle to each other in each block, the ends ot one tie-rod being positioned adjacent to the liange on the same side of each rail, and the ends of the other' rod being positioned adjacent to the flange on the opposite side of each rail from the ends of the first rod.

4. A railway tie including a concrete bloclr having a plurality of reinforcing members embedded therein, the middle portion of the reinforcing members beingsubsta-ntially parallel to the bottom 'face ot the 'block and adjacent thereto, thence being bent upwardly and outwardly, and then upwardly and inwardly to a point near the upper tace, and the ends extending toward each other and substantially parallel with the upper face of the block.

5. A railway tie including a concrete block having a plurality of reinforcing members spaced from each other and lying parallel to the lower face of the block at their middle portion7 the end portions being bent upward, first extending outwardly and then inwardly, and then bent with the ends toward each other, and an additional reinforcing means secured to the first mentioned reinforcing members at their centralportion to maintain them in position during the formation yof thevblock and serving as tension members at the point of greatest strain.

6. A railway tie comprising two concrete blocks each supporting a single rail and reof the tie rods reaching above each block av sutlicient distance to pass through a cushion block and a clamping bloei-, and to receive a locking means.

ln testimony whereof l atlix my signature in presence of two witnesses.
